Insecticidal pour-ons that are applied directly to cattle have been promoted widely in the last decade as a new means of controlling tsetse flies in Africa. Tsetse attracted to treated cattle get a lethal dose of insecticide and die. Following a large trial in Kenya, Matthew Baylis and Peter Stevenson argue here that the reduction in trypanosomiasis incidence caused by pour-ons exceeds that expected from the impact (if there is any) on the tsetse population and that certain other (as yet unknown) factors must also be involved.
在过去十年里，直接用于牛身上的杀虫浇泼剂作为在非洲控制采采蝇的一种新方法得到了广泛推广。被处理过的牛吸引来的采采蝇会摄入致死剂量的杀虫剂并死亡。在肯尼亚进行了一项大型试验之后，马修·贝利斯和彼得·史蒂文森在此指出，浇泼剂导致的锥虫病发病率的降低幅度超过了仅从其对采采蝇种群的影响（如果有任何影响的话）所预期的程度，一定还有其他某些（尚未知晓的）因素也在起作用。
